"This instance has set a bad precedence, which is not good for democracy," he said here, adding that Naidu should have followed proper procedures before rejecting the notice.

"There are procedures in the Constitution and chairman of Rajya Sabha should have followed it instead of acting in a hurried manner," Chatterjee said. Referring to previous instances of impeachment notices, Chatterjee said procedures were then followed properly.

Naidu rejected today the unprecedented impeachment notice given by Opposition parties, led by the Congress, against CJI Dipak Misra, saying it "lacked substantial merit" and allegations were neither "tenable nor admissible".

The vice-president held that the allegations emerging from the present case have a serious tendency of "undermining" the independence of the judiciary.
